This application presents the periodic table of the chemical elements.
The periodic table of the chemical elements is a tabular display of the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring ("periodic") trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior.
- The periodic table (zoomable and in some devices pinch-zoomable)
- Descriptions and illustrations of the elements (touch element for information)
The following properties are displayed for each element if the value is currently known by science.
Group, Standard atomic weight
Electrons per shell
Phase, Density (near r.t.)
Heat of fusion
Heat of vaporization
Specific heat capacity (25 ∞C)
Van der Waals radius
Electrical resistivity (20 ∞C)
Thermal conductivity (300 K)
Thermal expansion (25 ∞C)
Speed of sound (thin rod)
CAS registry number
